- DROP CHECK-VALVE.

SPECIFICATION forming part of Letters Patent No. 290,281, dated December18, 1883-. Application filed March 30, 1881. (Model.)

To all whom it may concern Be it known that I, MORRIS D. TEMPLE, ofChicago, in the county of Cook and State of Illinois, have inventedcertain new and useful Improvements in Drop Check-Valves; and I herebydeclare the following to be a full, clear, and exact descriptionthereof, which will enable others skilled in the art to which myinvention relates to make and use the same, reference being had to theaccompanying drawings, forminga part hereof, and in which Figure 1represents a sectional elevation of the apparatus cut through itslongitudinal center, except that part of the stem f below the plate h.Fig. 2 represents a plan view of the spider Z. Fig. 3 is a plan view ofthe ring upon which is formed the valve-seat, and to which are attachedthe arms (Z and hub e, and from which the dovetailed rubber ringB isremoved. Fig. 4 is a vertical section of a pump, showing its interiorconstruction, with my improved check-valve in place and hitched to thepumpbucket, ready to be removed from its seat.

Like letters of reference indicate like parts.

My invention relates to an improved form of drop check-valve providedwith an improved removably-attached and elastic packing-ring, and anarrangement by means of which the whole apparatus may be removed fromthe pump, substantially as hereinafter described.

In the drawings, 9 represents an annular ring formed on its exteriorcircumference into a dovetail, 9 upon which is sprung a rubber ring, B,provided with a dovetail groove adapted to fit on the dovetail 9.

Upon the inner circumference of the ring g are attached arms d,sustaining the central ring or hub, e, and the top of the ring 9 isformed into a valve-seat, g.

Through the hub e is passed a loosely-fitting stem, f, provided at itslower end with aknob, which limits theupstroke of the valve, and at asuitable distance above the knob is formed a shoulder, upon which restsan annular metal ring, h,\vhich supports an annular leather or rubberring, Z,which forms the packing for the valve j uponi ts seat 9, andwhich, with the parts t and h, are held on the stem f by the nut Thestem f rises above the nut is to aheight in about the proportion asshown, upon the end of which is secured a spider, Z, the arms of whichcurve downward, so as to form hooks, as shown.

Upon the outer circumference of the ring g is sprung a rubber ring, B,provided with a v dovetailed groove to fit over the dovetail g of thering 9, by means of which said ring is firmly held in place, it,with thering 9, being made of a size to fit into the conically-contracted part rof the pump-barrel or bucket-chamber P, as shown.

To the lower end of the pump -bucket 0 is attached a bail, m, by thecars a. The bucket 0 is arranged to play high enough above the spider Z,so as to prevent the bail m from being caught on its arms in itsordinary working motions.

Within and between the inner circumference of the ring hub e, and arms(Z are formed the water-ways. The ring 9, with its arms d and hub 6,forms a wheel, (designated by the letter A,) ,and the completeapparatus, as shown in Fig. 1, is designated by the letter A.

The manner of applying and using my improved drop check-valve is asfollows, to wit: The apparatus A is lowered or dropped into the pump 1?in its proper vertical position, as shown in Fig. 4, when it will, bymeans of its elastic packing B and the water-pressure, when in use, seatitself against the conical sides 0', and form with them a water-tightjoint. When from accident or wear the valve fails to work, it may beremoved from the pump by either raising the handle to its extremeheight, or by removing it from its fulcrum, so that it may be lowered,and so that the bail in may catch over one of the arms of the spider Z,after which it may be replaced, and by then drawing the handle down, thevalve may be lifted from its seat and the pump-bucket, with it attachedthereto, removed from the pump without in any manner disturbing anyotherparts of the pump.

It is not absolutely necessary that the hooks to catch 011 the bail m beattached to the valvestem, for they may also quite as readily underdifferent forms be attached to the ring 9 outside of the valve-seat.Byattaching a swinging bail to the lower end of the pump-bucket, asherein shown,the check-valve may be caught and raised by it, by simplylifting the end of I00 the handle high enough orlowering it in its slotfar enough for the bail to pass down under the hooks of the check-valve;but the handle does not require to be taken out or from the piston-rodin order that the bucket may be turned around by the piston-rod until aclaw or threaded device attached to the valve may catch with a fixedhook attached to the lower end of the pump-bucket. Of thelatter, thereare several varieties; but I disclaim all such contrivances.

\Vhat I claim as new is- 1. The wheel A, provided with valve-seat g anddovetailed rim 9, in combination with the dovetailed rubber packing 13,substantially as herein shown and described.

2. The wheel A, provided with the valveseat 9, in combination with valvej, provided with stem f and spider Z, constructed substantially as andfor the purpose specified.

3. The wheel A, provided with valve-seat g, and rubber packing B, incombination with the valve j, provided with valve-stem f and spider Z,constructed substantially as and for the purpose specified.

i. The apparatus A, provided with upwardprojecting, hooks, incombination with aloucket, 0, and dependent swinging bail m.

5. The drop check-valve A, provided with upward-proj ecting hooks, incombination with a bucket, 0, provided with dependent swinging bail on,and pump P, havingconical seat 0'.

6. The bucket 0, provided with a bail, m, in combination with the wheelA, provided with suitable hooks to engage with the bail m, andvalve-seat 1 valve j, stem f, and packing B, constructed and arranged tooperate substantially as and for the purpose specified.

7. A drop check-valve provided with a series of hooks, in combinationwith a bucket I having a dependent swinging bail, to operatesubstantially as specified.
